MediaGauge? (Model MG1-9V) Digital Pressure Gauge
Product Overview
Since piezo resistive pressure sensors are sensitive to
changes in temperature, the MediaGauge? MG1-9V uses
signal conditioning to compensate for temperature and
calibration. The output signal is then converted into one of 3
user selectable forms (select units with the ON/UNIT/OFF
button):
1) PSI
2) BAR
To manually power down the unit: Press the ON/UNIT/OFF
button and hold down for 3 seconds until OFF is displayed and
then release the button.
The LIGHT/P-H (Peak-Hold) button is used to turn the LCD
backlight on/off and to display the maximum peak pressure the
unit has measured.
To turn the LCD backlight on : Press the LIGHT/P-H button once.
3) MPA (kg/cm2)
To turn the LCD backlight off: Press the LIGHT/P-H button
The MediaGauge? MG1-9V will display the pressure
reading after the ON/UNIT/OFF button is depressed. The
pressure measurement reading is updated 3 times per
second.
again.
To see the maximum peak pressure the unit has measured:
Press and hold down the LIGHT/P-H button for 3 seconds. The
maximum pressure reading will be blinking.
If the maximum
pressure read was over the unit’s maximum pressure range, o.L
MediaGauge? MG1-9V Panel
MediaGauge? MG1-9V panel has a LCD display and three multi-
functional buttons – ON/UNIT/OFF; LIGHT/P-H (Peak-Held) and
RESET/CLEAR.
The ON/UNIT/OFF button is used to display the pressure

To return to the current pressure reading: Press the LIGHT/P-H
button and hold down for 3 seconds.
The RESET/CLEAR button is used to reset the gauge to
whatever pressure is currently applied to the port and to clear the

then you press and hold the RESET/CLEAR button for 3 seconds
the display will show 0.0 psi. A measurement of 30 psi would then
read as 10 psi on the display.
